e) Pump-Out Frequency Control (dip switch 5 & 6)
The pump motor drains the water tank at the frequency set by the pump-out frequency 
control.
The pump-out frequency control is factory-adjusted to drain the water tank every 0 
cycles, and no adjustment is required. However, where water quality is bad and the 
icemaker needs a pump drain more often, the pump-out frequency can be adjusted as 
shown in the table below.

f) Freeze Timer (dip switch 9 & 10)
CAUTION
Adjust to proper specification, or the unit may not operate correctly.
The freeze timer setting determines the maximum allowed freeze time to prevent 
possible freeze-up issues. Upon termination of freeze timer, machine initiates the harvest 
cycle. After  consecutive timer terminations, machine will shut down, possibly indicating 
a problem.
The freeze timer is factory adjusted and no adjustment is required.

g) Bin Control
CAUTION
When the ambient temperature is below 45°F (7°C), the bin control thermostat 
operates to stop the icemaker even if the ice storage bin is empty. When the 
thermostat is set in the prohibited range, the icemaker operates continuously 
even if the ice storage bin is filled with ice. Setting in the prohibited range might 
cause severe damage to the icemaker resulting in failure.
No adjustment is required under normal use, as the bin control is factory-adjusted. Adjust 
it, if necessary, so that the icemaker stops automatically within 0 seconds after ice 
contacts the bin control thermostat bulb.
